54CHAPTER 3: SYSTEM MANAGEMENT

The names of the program/configuration file are “system” and “config” respectively by default. In the command, file-nameis a character string with the length of 1 to 30.

2Set FTP update mode

When logging onto the FTP Server from a PC, you can use the put command to upload the file. The FTP Server adopts two update modes: fast update mode and normal update mode.

■Fast update mode: In this mode, after the FTP Server has received the files uploaded by the user, it will write the files into Flash. Even when the power is disconnected during the period of transmitting the files, the existing files in the router will not be destroyed.

■Normal update mode: In this mode, the FTP Server writes the files uploaded by the user into Flash as it receives the files. The existing files in the router may be destroyed due to power disconnection. Compared with fast update mode, the system demands less empty memory in the router when working in normal update mode.

Please perform the following configuration in system view.
